Shrub rose plant named &#39;MEIPINAPIO&#39;

ABSTRACT

A new and distinct variety of landscape shrub rose plant is provided which abundantly forms in clusters on a nearly continuous basis attractive small ochre-pink blossoms. The plant exhibits a low, compact and bushy growth habit. Good disease tolerance including resistance to Black Spot has been observed. The attractive dark green foliage contrasts nicely with the blossom coloration. The new variety is particularly well suited for growing as attractive ornamentation in the landscape.

BOTANICAL/COMMERCIAL CLASSIFICATION

Rosa hybrida/Shrub Rose

VARIETAL DENOMINATION

cv. Meipinapio

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida landscape shrub rose plant is provided. The new variety is believed to be a spontaneous mutation of unknown causation of the ‘Meigalpio’ variety (U.S. Plant Pat. No. 17,877, granted Jul. 24, 2007). A single plant of the new variety was discovered while growing in a nursery setting at Le Cannet des Maures, Var, France, among a block of plants of the ‘Meigalpio’ variety. The plant was found to display a distinctive dissimilar blossom coloration and was thereafter carefully studied. Had this plant not been discovered and thereafter preserved it would have been lost to mankind.

It was found that the new variety of the present invention

(a) exhibits a low, compact and bushy growth habit,

(b) abundantly forms in clusters on a nearly continuous basis attractive small light ocher-pink blossoms unlike the brilliant red-pink blossoms of the ‘Meigalpio’ variety (U.S. Plant Pat. No. 17,877),

(c) forms dense dark green foliage having a glossy aspect that contrasts well with the blossom coloration, and

(d) is particularly well suited for growing as attractive ornamentation in the landscape.

The tolerance to diseases is good. During observations to date the plant has been found to be particularly resistant to Black Spot.

The new variety well meets the needs of the horticultural industry and can be grown to advantage in parks and gardens where attractive ornamentation is desired.

The new variety readily can be distinguished from its parent ‘Meigalpio’ variety in view of its distinctive light ocher-pink blossoms.

The new variety also can be readily distinguished from ancestors of ‘The Fairy’ variety (non-patented in the United States), the ‘Kormax’ variety (non-patented in the United States), and the ‘Morpapplay’ variety (United Plant Pat. No. 6,548). ‘The Fairy’ variety forms dissimilar light pink blossoms, the ‘Kormax’ variety forms larger red blossoms having only six petals, and the ‘Morpapplay’ variety forms dark orange-red blossoms having a bright yellow eye.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and the use of cuttings. Asexual propagation by the above-mentioned techniques in France has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety can be asexually reproduced in a true-to-type manner.

The new variety has been named ‘Meipinapio’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were approximately eighteen months of age and were observed during October while reproduced by the use of cuttings and growing outdoors at Le Cannet des Maures, Var, France. Standard colors are presented at the bottom for comparative purposes.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart—1995 or equivalent). The description is based on the observation of eighteen month-old plants during October while growing on the plant's own roots outdoors at Le Gannet des Maures, Var, France.
